Recovery and re-use of resources from digested urban waste in the context of the circular economy
Type of activity
Funding entity code
DigesTake is an industrial research project with the end goal of developing new processes and technologies for treating, recovering and reusing resources from effluent liquids and gases (waste gas from biogas) resulting from anaerobic digestion in wastewater treatment plants, following the principles of environmental sustainability and energy efficiency. Enabling technologies common to other areas, such as biotechnology, advanced materials and ICT, will be applied to meet technological challenges involving multiple disciplines and areas of expertise (chemical engineering, electronics, materials science, automation, electrochemistry, microbiology) through laboratory-scale and pilot experiments. The research activity will be carried out within four large areas or activities: "carbon" (Activity 1), "phosphorous" (Activity 2), "nitrogen" (Activity 3) and "water and nutrient concentration" (Activity 4). The "carbon" activity will focus on converting carbon dioxide from the biogas into added-value organic compounds using bioelectrochemical systems. Two alternative processes are proposed to recover phosphorous (A2): recovery of struvite using byproducts from the mining industry as reagents; and a new process of bio-induced precipitation of phosphorous in a partial nitration-anammox (PNA) reactor. At the same time, a system of environmentally sustainable biosensors will be developed to measure phosphorous in situ in order to monitor the processes. The activity "nitrogen" includes recovery of ammonium salts using adsorption-desorption systems with rechargeable zeolites and a process for removing the excess nitrogen content in water with low energy consumption in micro-aerophilic conditions. Finally, activity 4 ("water and nutrient concentration") will involve research on membranes and extraction solutions in a directosmosis process. The project is expected to have a major scientific, technological, environmental and economic impact throughout the value chain of wastewater recovery (operators and builders of wastewater treatment plants, service companies, public authorities) but also for...
